Double suction pumps easily provide higher flow as compared to single suction pumps, due to the reduced axial force
. As a result of reduced axial force
, double suction pumps face less wear and tear in comparison with others.
However, the axial force
in the longitudinal direction may induce tensile stresses in the lining which may be the cause of secondary effects such as water inflow, leakage, etc.
Buckling not only leads to the increase of contact force and friction, also impacts the axial force
transfer and exerts the difficulty of well trajectory control.
Based on existing literature a force having magnitude 10% value of the axial force
is applied perpendicular to the axis of the shaft.
It has been widely recognized by researchers that the axial force
is a critical parameter for evaluating rock bolt performance.
In the case of positive resultant thrust (case B, [T.sub.t] < 0), equation (2) yields that the constraint modeling the main thrust bearing in Figure 1 must be (4B); that is, the axial force
exerted by the bearing on the impeller is positive ([F.sub.a] > 0).
Because the internal forces (axial force
) are related only to the deformation of the bar element, it is necessary to remove rigid body translations and rotations from the relative displacement.
Under the action of vertical seismic waves, the axial force
of left tunnel lining is pressure, the maximum pressure is on the right arch foot, and its value is 458.8 kN.

Gopalakrishnan and Murugan  developed an empirical relationship to predict the strength of friction stir welded AA6061/ 3-7 wt % TiC and described the effect of welding speed, axial force
, tool pin profile and weight percentage of TiC particles.
Moment-curvature analysis of cross-sections is of prime importance in the analysis of inelastic behaviour of cross-sections subjected to bi-axial loading and axial force
. Such analyses will reveal the strength, ductility, energy dissipation capacity and also the elasto-plastic rigidity of a cross-section section at a specified level of external loading.
It is supposed that the permissible axial force
reaches 70% of the radial load unused.
